Question

To save money, a local charity organization wants to target its mailing requests for donations to individuals who are most supportive of its cause. They ask a sample of 5 men and 5 women to rate the importance of their cause on a scale from 1 (not important at all) to 7 (very important). The ratings for men were

M₁ = 6.2.

The ratings for women were

M₂ = 5.4.

If the estimated standard error for the difference

(s_{M1 − M2})

is equal to 0.25, then consider the following.
